Description

Foldable personal carrier

Technical Field

The subject matter of the present application relates to foldable personal carriers, particularly in the field of children's toys and carrier products.

Background

Foldable personal vehicles, such as scooters, vehicles and bicycles, are well known to both adults and children. For children, carriers are sometimes folded up for compact storage and carrying.

Many such foldable carriers are known, centered on two basic principles: and (4) disassembling and folding. In the case of the first group, the carrier is disassembled into basic parts that can be assembled together compactly. In the case of the second group, most of the components of the vehicle maintain their interconnection, but may be in an operative condition, in which they act as a vehicle and a store, and a folded condition, in which the orientation and/or position of the components are changed relative to each other.

Vehicles of the second group mentioned above are described, for example, in US 6152473, US 6530589 and http:// www.iimo-life. com/vehicle2_01.htm, which are products sold as IIMO folding tricycles.

The presently disclosed subject matter relates to the vehicle of the second group described above.

Disclosure of Invention

The subject matter of the present application relates to a foldable personal carrier having an operative state and a storage state, wherein it can take a very compact form. The longitudinal axis of the vehicle lies within its vertical plane of symmetry and has a horizontal reference plane perpendicular to the plane of symmetry, and the vehicle in the stowed state assumes its compact form both along the plane of symmetry and along a vertical plane perpendicular to the plane of symmetry, both in a direction along its longitudinal axis and in a direction perpendicular to the axis.

According to a first aspect of the presently disclosed subject matter, the vehicle may include:

-a body member having an upper surface for holding a seat, front and rear ends spaced from each other along a longitudinal axis, a right and left rear side surface, both arranged adjacent to the rear end of the body member and spaced from each other in a direction perpendicular to the plane of symmetry;

-a front bar and front wheels mounted on the front bar, the front bar being at least indirectly pivotably hinged to the body member adjacent the front end thereof to obtain a working orientation and a storage orientation;

-a right rear leg and a left rear leg, each leg having a leg distal end with a rear wheel and a leg proximal end at which the legs are pivotally hinged to respective rear side surfaces of the body member to obtain a working orientation and a stored orientation, at least one leg having a connection region between the leg proximal end and the leg distal end; and

at least one connecting member at least indirectly connecting the front bar with the connection region of said at least one leg, such that pivoting of the front bar between its working and storage orientations causes said at least one connecting member to pivot the rear legs along the respective rear side surfaces of the body member between their respective working and storage orientations.

As a result of the proximal ends of the rear legs being pivotally hinged to the right and left rear side surfaces of the body member and such hinging using the above-described connecting regions and connecting members, the rear legs of the carrier may be free of any common elements extending therebetween for pivotally connecting the legs to the body member at locations where they are spaced from the proximal ends of the legs. This allows the pivoting angle of the rear legs to be so large that in the stowed state of the carrier the rear legs can occupy a position in which at least a majority of the area of each leg overlaps at least a majority of the area of the body member, as can be seen in the side view of the carrier, thereby allowing in this state a significant reduction in the dimension of the carrier along the longitudinal axis of the carrier and perpendicular to this axis along its plane of symmetry. This means that in the stowed state of the vehicle, each rear leg may be fully or almost fully coextensive with the body member at least along a majority of its longitudinal dimension, e.g. each rear leg may have its distal end proximate to the front end of the body member to the extent that end (not including the associated rear wheel) does not project significantly forward from the front end of the body member. If this is the case, the front bar is of a type such that, as seen in a side view of the vehicle in its stowed condition, in its stowed orientation the front wheels are disposed forwardly of the body member, at least a majority of each rear leg together with the associated rear wheel may be accommodated between the rear end of the body member and the front wheels, thereby allowing the length of the vehicle along its longitudinal axis in this condition to be significantly reduced.

In view of the above, the shape and width of each leg portion with respect to the body member may have the following shape and width: as seen in the side view of the vehicle, in the stowed state of the vehicle, each leg may overlap not only along a substantial part of their length as described above but also along a substantial part of their height, i.e. in a direction perpendicular to the longitudinal axis and along the plane of symmetry, allowing the overall height of the vehicle to be significantly reduced in that direction in the stowed state.

The pivotal articulation of each of the right and left rear legs of the vehicle relative to the respective rear side surface of the body member may be provided by a respective articulation axis having an exterior portion of: the outer portion projects from an associated posterior surface of the body member and is freely received in a channel formed at the proximal end of the posterior leg, the channel extending between the medial and lateral surfaces of the posterior leg. The hinge shafts may each be integrally formed with the body member or fixedly mounted to the body member through the inside of the shaft. In any case, the exterior of each shaft, i.e., the portion of each shaft that protrudes from the associated rear side surface of the body member, may be configured to enter the channel from the inside surface at the proximal end of the leg and fixedly engage a stop disposed adjacent the outside surface of the leg by its shaft free end to allow the leg to pivot about the shaft while preventing the leg from being removed from the shaft. This may be accomplished, for example, by configuring the shaft-engaging end to be threaded into a corresponding nut that constitutes a stop and is received within a pocket in the outer side surface of the leg proximal end.

Alternatively, each hinge shaft may protrude from, be integrally formed with, or fixedly mounted to the inside surface of the proximal end of the respective rear leg, and may be pivotably received within the body member at the respective rear side surface.

The right and left hinge axes may be spaced from or meet at a plane of symmetry of the carrier. In the latter case, as described above, the two hinge shafts may be formed as a single shaft body having a central inner portion disposed within the body member and two outer portions protruding from the rear side surface thereof.

The inner and outer portions of each hinge axis may be collinear and extend along a single rear pivot axis, or they may be angled with respect to each other.

The hinge axes of the two rear legs, or at least their outer portions, can extend along their respective rear pivot axes at a non-zero angle therebetween, each axis intersecting the rear side surface of the body member at a respective right and left rear hinge point.

The rear pivot axes of the two legs may each form an acute angle with the reference plane when viewed in a rear view of the vehicle. This may allow the spacing obtained between the distal ends of the rear legs when the rear legs are in the working orientation to be greater than the spacing between the distal ends of the rear legs when the pivot axis lies in a plane parallel to the reference plane.

Additionally or alternatively, each of the right and left rear pivot axes may be oriented at an acute angle relative to a plane of symmetry of the vehicle. In this case, pivoting of the rear legs about the rear pivot axis from the working orientation to the stowed orientation may allow their distal ends to be closer to the plane of symmetry, e.g. their distal ends to be spaced from the plane to the same or about the same extent as their proximal ends to the plane, thereby improving the "stowed state" compactness of the vehicle in a direction perpendicular to the plane of symmetry.

In the case of a pivot axis forming an acute angle with the plane of symmetry and with a plane perpendicular thereto, the above-mentioned "stored state" compactness is achieved despite the increased spacing between the distal ends of the rear legs in the operating state of the vehicle.

The body member may have a front body portion having a right and left front side surface thereof and a rear body portion having a right and left rear surface. The right left front side surface can be arranged closer to the symmetry plane than the right left rear side surface, i.e. the rear body portion is wider than the front body portion in a direction perpendicular to the symmetry plane.

Additionally, the rear portion of the body member may have a converging configuration as seen in at least one of a plan view and a rear view thereof, provided by a respective orientation of right and left rear side surfaces of the rear body portion. In this case, the inner side surface of each rear leg adjacent its front proximal end may be oriented in the same manner as and coextensive with the respective rear side surface of the body member, such that these surfaces are in intimate contact in both the stowed and operative states of the vehicle. For example, each of the posterior surfaces of the right-left pair of contacting body members and the medial surface at the proximal end of the posterior leg may be oriented such as to provide one or both of the aforementioned acute angles of the right-left pivot axis, in which case these axes may be perpendicular to the respective contact surfaces.

The body member may be in the form of a unitary body, or it may be assembled from multiple elements. For example, these elements may comprise right and left body halves assembled such that their edges meet at a plane of symmetry of the carrier and define an at least partially hollow interior therebetween.

The front bar may extend along a front bar axis between a front wheel end of the front bar associated with the front wheel and a handle bar end associated with the handle bar. In the working orientation of the rod assumed by the front rod in the working state of the vehicle, the front rod axis may form an angle with the longitudinal axis of the vehicle that is significantly greater than the angle that the front rod axis may form with the longitudinal axis of the vehicle in the stowed orientation of the front rod acquired by the front rod in the stowed state of the vehicle. In particular, the arrangement may be such that in the stowed orientation of the front bar axis forms an angle of no more than 25 degrees, more particularly no more than 20 degrees, still more particularly no more than 15 degrees with the longitudinal axis optionally, in the stowed state of the vehicle, the front bar axis may be parallel or nearly parallel with the longitudinal axis.

The front bar may form part of a front assembly that further comprises a hinge member by which the front bar is pivotably connected to the front end of the body member about a front pivot axis and which is connected to one or more link members. The front pivot axis may be spaced from the front rod axis such that in an operative orientation of the front rod in an operative state of the vehicle, the front rod is disposed forward of the body member, and in a stowed orientation of the front rod in a stowed state of the vehicle, the front rod is disposed above the upper surface of the body member and extends along at least a majority of a length of the front rod along the upper surface of the body member.

With the above configuration, the front bar may be oriented in the stowed state of the vehicle to be spaced upwardly from the longitudinal axis by a distance shorter than the distance of the highest point of the vehicle, except for any point of the front bar itself. For example, the highest point may be the highest point of the front wheels and/or the seat in the stowed state of the vehicle.

The hinge member may have: a front-lever associating portion that surrounds the front lever in a manner that allows the front lever to swivel about a front-lever axis; a rear leg associated portion to which the at least one connecting member is attached at an end thereof opposite to an end thereof connected to a connecting region of the rear leg; and a body member associated portion at which the hinge member is pivotally hinged to the front end of the body member.

The at least one connecting member may be made of a rigid material such that the length of the at least one connecting member remains constant during operation of the vehicle and when the state of the vehicle changes. More particularly, the connecting member may be sufficiently rigid to be able to push the rear leg from its stored orientation to its operative orientation when pushed by the hinge member. The carrier may include two such connecting members, namely a right and left connecting member, each connecting the hinge member with the connecting region of the respective right and left rear leg portions.

The vehicle may also include pedals that are removably mounted to or integrally assembled with the front wheels.

The carrier may also be configured for adjusting the position of the seat along the body member.

The vehicle may be configured to allow its user to occupy the seat to manipulate the vehicle by himself or to prevent such manipulation by the user, while allowing manipulation of the vehicle from behind the vehicle by manipulation of the manipulation handles by others. In this case, the carrier can have one or more of the following features:

a non-integral design of the front bar, the upper and lower parts of which can be locked to each other to function as a single integral unit that can be manipulated by operating the handle bar and unlocked from each other to allow manipulation of the lower part by a separate manipulation mechanism that does not include the upper part and to allow the desired function of the upper part to be achieved without affecting the manipulation of the lower part;

a front bar locking clamp for locking the front bar at least upper to an element of the vehicle (such as for example its fixed frame) that is immovable in the operating condition of the vehicle to prevent the possibility of rotating the front bar or its upper part about the front bar axis by operating its handle bar;

-a foldable rear steering mechanism for use with a rotatable rear steering handle when mounted to the rear end of the body member, the mechanism connecting the handle with the front bar or with at least a lower portion of the front bar such that manipulation of the handle causes the front bar or a lower portion thereof to rotate about the front bar axis to steer the vehicle;

-a footrest fixedly mounted at least indirectly to the body member at a position closer to the seat than to the front wheel; this position may be on the hinge member, more particularly at its body member-related part or its rear leg-related part or between these two parts; the footrest may be constituted by the above-mentioned pedals (when they are detached from the front wheels).

The vehicle may have any design of steering mechanism that allows the lower front rod portion to pivot between its operating and stowed orientations. According to one example of such a design, the steering mechanism may comprise the following elements:

-a front rotary member fixedly mounted to the front rod;

-a rear rotatable port located at the rear end of the body member and configured to fixedly receive a rear manoeuvring handle therein such that rotation of the handle about the handle axis causes corresponding rotation of the port; and

The right and left cable sections may extend along and within the body member of the vehicle for a majority of their lengths. The right and left cable sections may be part of one cable fixedly connected to the front swivel and the swivel port.

Detailed Description

The figures listed above illustrate a number of children's tricycles, each referred to throughout the specification as a "carrier," including carrier 1 shown in fig. 1A-3E, carrier 100 shown in fig. 4A and 4B, and carrier 200 shown in fig. 5A-5C. Each of

carriers

1, 100 and 200 has a longitudinal axis L lying in a plane of symmetry SP of the carrier, and the carrier is foldable between its operating state and stowed state:

in the operating state, the ride-on vehicle can be driven along a plane perpendicular to the plane of symmetry and referred to in this description as reference plane RP, and

in said stored state, the carrier can be freely placed on the reference plane RP, so that its longitudinal axis L forms an angle LR with this plane which does not exceed, or at least does not substantially exceed, the angle formed between them in the operative state of the carrier.

The longitudinal axis, the plane of symmetry, the reference plane and the storage state of the vehicle are only shown in the figures with respect to the vehicle 1, the description of the vehicle 1 being fully applicable to the

vehicles

100 and 200.

Referring to fig. 1A, a vehicle 1 includes a rigid body member 10, a seat device 30, a front wheel W having pedals P_FFront assembly 50, with corresponding rear wheel W_RRAnd W_RLRight rear leg portion 70_RAnd a left rear leg 70_LAnd a connecting mechanism 90. Since the rear legs and their rear wheels are of identical design, they are designated by a single reference numeral 70 in the figures other than fig. 1A, and their wheels are designated hereinafter as W_R。

Referring to fig. 1B and 1G, the body member 10 includes a front body portion 11_FAnd a rear body portion 11_RThe front main body part 11_FIncluding a front body end 12_FThe rear body part 11_RIncluding a rear body end 12_RThe front and rear portions have a fixed mutual arrangement in the operating state and in the stored state of the vehicle. The body member may be in the form of a unitary body or more precisely it may be assembled from a plurality of elements.

As shown in fig. 1B, the body member 10 includes: an upper surface 13 facing upwards or away from the reference plane RP; a lower surface 14 facing downwards or towards the reference plane RP; right and left anterior side surfaces 15_FExtending between the front portions of the upper and lower surfaces of the body member and defining a front body portion 11_F(ii) a And right and left rear side surfaces 15_RExtending between the rear portions of the upper and lower surfaces of the body member and defining a rear body portion 11_RThe rear leg 70 is pivotally hinged to the rear body portion 11_F. As best shown in FIG. 1G, the right and left front sides 15 of the body member 10_FMore right and left rear side surface 15_RCloser to the symmetry plane SP, which means that the rear body part 11_RIn a direction perpendicular to the symmetry plane SP than the front body part 11_FIs wider.

As best shown in fig. 1A and 1C, the seating arrangement 30 includes a seat 32, the seat 32 being mounted to the upper surface 13 of the body member 10 so as to be at least partially defined by the rear body portion 11_RAnd (4) supporting. The seat device may be configured to cover the rear body portion 11 to different degrees in the area of the seat_RIs mounted at one of at least two different locations along the body member.

The seating unit 30 further includes a backrest 34, the backrest 34 having: a fixed backrest portion 35 integrally assembled or formed with the seat 32; and a foldable backrest portion 37. The backrest part 37 can be pivoted about an axis X parallel to the reference plane RP and spaced from the seat 32 by the fixed seat part 35_BRThe backrest part 37 is pivoted between a substantially upright orientation in the operating state of the vehicle 1 and a substantially horizontal orientation of the backrest part 37 in the stowed state of the vehicle. In addition, the backrest portion may be configured to adopt at least two different upright positions to allow for selection of more convenient support of the rider/user's back in the operative state of the vehicle.

The seating arrangement 30 also includes an optional fixed frame 36, in this example the fixed frame 36 may be about the same axis X as the pivoting back portion 37_BRThe fixed frame 36 can prevent a child sitting in the seat 32 from falling off the carrier 1 in a substantially horizontal working orientation, pivoting between its substantially horizontal working orientation, in which it can prevent the child from falling out of the carrier 1, and a substantially vertical non-working orientation used during folding of the carrier. The fixed frame may be configured to be removably attached to the carrier.

The seat may be formed without a fixed part and/or a fixed frame and the foldable back part may have a different axis about which the back is pivotable, with the pivot axis of the back being arranged closer to the seat than the axis of the fixed frame in the operational state of the vehicle. The backrest may be made of a rigid material, or it may be in the form of a fabric shell configured to be worn over a backrest frame (not shown) which may be permanently pivotally mounted to the seat, or which may be removably attached to the seat when it is desired to bring the vehicle into its operative condition.

The rear body portion 11 will now be described in more detail with reference to fig. 1B, 1F, 1G and 1H_RAnd the rear leg 70 is pivotally hinged to the rear body portion 11_RThe method (1).

Due to the right and left rear side surfaces 15_RIn the corresponding orientation of the rear body portion 11_RAs seen in its plan view (fig. 1G) and rear view (fig. 1F) have a converging configuration. More specifically, these surfaces 15_RIs inclined so as to face away from the rear body end 12_RThe direction (fig. 1G) and the direction away from the reference plane RP (fig. 1F) are closer to each other.

Referring to FIG. 1H, the back side surface 15 of the body member 10_RAre respectively provided with hinge shafts 16, the hinge shafts 16 being fixedly mounted to the rear body portion 11_R(only the right axle is seen) so that its outer portion 18 with its free end 19 projects from the rear side surface for retaining the respective rear leg 70 thereon. Each outer portion 18 of hinge axis 16 is perpendicular to relative rear side surface 15_ROriented corresponding pivot axis X_RPExtends and is at a rear hinge point P_RA(only one such point is seen) to intersect the surface. Two right and left rear side surfaces 15_RRear hinge point P_RAMay be positioned such that an imaginary line connecting them intersects the longitudinal axis L of the carrier (not shown).

Rear side surface 15_RIs oriented so that the rear axis X is perpendicular thereto_RPForming a desired angle with the reference plane RP. More specifically, as shown in FIG. 1F, the rear pivot axis X_RPEach forming an acute angle alpha with the reference plane RP. This allows the pivot axis X thereof with respect to the same leg between the distal ends of the rear legs (in their working orientation)_RPAn increased spacing S is obtained as regards the spacing that would have been present when lying in a plane parallel to the reference plane RP. Further, as shown in FIG. 1G, each pivot axis X_RPOriented at an acute angle beta with respect to the symmetry plane SP of the carrier. This ensures that the rear legs are about the rear pivot axis X_RPFrom the working position to reservePivoting of the positions results in their distal ends being closer to the plane of symmetry such that their distal ends are spaced from the plane to the same or approximately the same extent as their proximal ends are spaced from the plane, despite the aforementioned increased spacing S. Moreover, in fact, thanks to the above-mentioned angle β, the distal ends of the rear legs may be even closer to each other than the proximal ends thereof in the stored orientation of the legs, thereby improving the "stored state" compactness of the carrier in a direction perpendicular to the plane of symmetry, as explained in more detail below with reference to fig. 3A and 3B.

With reference to fig. 1E, the handle bars 57 have, in their working orientation, a handle portion 58, which handle portion 58 extends substantially transversely to the plane of symmetry SP of the vehicle, so that their ends are maximally spaced from the front bar 52 and from the plane SP, and they can each extend about a handle bar axis X extending substantially parallel to the plane SP_HBRotated so that their ends can be spaced a minimum from the plane of symmetry SP in the stored orientation of the handle portion 58.

The wheel end 52A of the front lever 52 is formed with a rotatably held front wheel W_FThe fork 54. The pedals P are each held by a respective pedal shaft 53, the pedal shaft 53 being mounted to the front wheel through an opening in the fork 54 through which the pedal shaft 53 passes freely. Each pedal may be configured to pivot between its operating orientation oriented transverse to its axis 53 and its stored orientation aligned with that axis. The pedals, with their axles, can be removed from the front wheels.

Referring to fig. 1C, the front assembly 50 further includes a hinge member 60, the hinge member 60 being used to pivot the front lever 52 about the front pivot axis X_FPPivotally hinged to the front end 12F of the body member 10, the front pivot axis X_FPPerpendicular to the symmetry plane SP (and parallel to the reference plane RP), and the front pivot axis X_FPAt the front hinge point P_FWhere it meets each side 15 of the front of the body member 10.

With reference to fig. 1A, 1F and 1H, the hinge member 60 connects the front bar 52 with the connection region 78 of the leg 70 by means of two longitudinal connecting elements or bars 92, each longitudinal connecting element or bar 92 having: a front connecting end 92A, which front connecting end 92A is attached to one side of the rear leg-associated portion 66 of the hinge member 60 so as to enable the connecting element 92 to be movable about the front connecting axis X with respect to the rear leg-associated portion 66_FCPivoting; and a rear attachment end 92B, the rear attachment end 92B being attached to the attachment region 78 of one of the legs 70 such that the attachment element 92 is capable of being attached relative to the rear leg 70 about a rear attachment axis X_RCPivoting. The connecting elements 92 are made of a rigid material so that their dimensions remain unchanged during their operation.

Reference is now made to fig. 2A to 2E, which illustrate the process of folding the carrier 1 from the operating condition shown in fig. 1A to 1F and 2A into the stored condition shown in fig. 2E, 3A and 3C. In fig. 1A to 1F and 2A the vehicle is shown in its operative state in which it can be ridden along a plane, the reference plane RP (shown in fig. 1F), and in fig. 2E, 3A and 3B the vehicle is shown in its stored state in which it can be freely placed on such a plane that its longitudinal axis forms an angle with the plane that does not exceed the angle formed between them in the operative state. The process is described below with reference to axes about which the elements of the vehicle 1 will pivot/rotate when bringing the vehicle 1 from its working orientation into its storage orientation, and with reference to fig. 2A, these axes are as follows:

handle bar axis X_HBThe handle lever 57 being about the handle lever axis X_HBRotating from their working orientation shown in fig. 2A, in which the grip portions 58 of the grip levers are arranged at their greatest distance from the front lever 52 and from the symmetry plane SP, to their storage orientation shown in fig. 2B, in which the grip portions 58 of the grip levers are arranged at their smallest distance from the front lever 52 and from the symmetry plane SP;

-a backrest axis X_BRAbout the backrest axis X_BR，

(a) The fixed frame 36 being about the backrest axis X_BRBetween its working orientation shown in fig. 2A, in which the fixed frame 36 forms a minimum angle with the reference plane RP, and its vertical orientation shown in fig. 2B, in which the fixed frame 36 forms a maximum angle with the reference plane RP, which also constitutes the storage orientation shown in fig. 2E; and

(b) the backrest part 37 being about the backrest axis X_BRFrom its generally vertical working orientation shown in figure 2A, in which the backrest portion forms the greatest angle with the reference plane, to its generally horizontal storage orientation shown in figure 2E, in which the backrest portion 37 forms the least angle with the reference plane;

-a front pivot axis X_FPThe front lever 52 is pivoted about the front pivot axis X by a hinge member 60_FPFrom its operative orientation shown in fig. 2A, in which front rod 52 forms a maximum angle with longitudinal axis L and with reference plane RP, Clockwise (CW) to its stored orientation shown in fig. 2DIn the stored orientation, the front rod 52 forms a minimum angle with the longitudinal axis L and with the reference plane RP; fig. 2C shows the intermediate orientation of the front link 52 achieved by the front link 52 before the front link 52 reaches its stored orientation during the above-described pivotal movement;

-a rear pivot axis X_RP(only one such axis is visible therein) about which rear pivot axis X the rear legs 70 are drawn by the hinge members 60 via the respective connecting elements 92_RPFrom the working orientation of the rear leg shown in fig. 2A, in which the rear wheel and the front wheel W are pivoted to the storage orientation of the leg shown in fig. 2E_FSpaced to the maximum extent in the leg reserve orientation, the rear wheels W_RWith front wheels W_FMinimally spaced; since the front link 52 and the rear leg 70 are connected to each other by the connection mechanism 90, the front link pivots about the front pivot axis X_FPCause each rear leg to rotate about their respective axis X_RPSimilar CW rotation of (c);

-front connection axis X_FCEach connecting element 92 being about the front connecting axis X_FCPivot relative to the hinge member 60; and

-rear connection axis X_RC(not shown in fig. 2A-2E), each connecting element 92 pivots about a rear connecting axis X when the front and rear legs pivot as described above_RCPivoting relative to the rear leg 70.

Thus, when folding the vehicle 1 from its working condition to its storage condition, first bring its handlebar into its storage orientation and the fixed frame into its vertical orientation as shown in fig. 2B, and then pivot the front and rear legs into their storage orientation as shown in fig. 2C and 2D; the backrest is then pivoted to its stored orientation and simultaneously or subsequently the fixed frame is pivoted to its horizontal orientation as shown in figure 2E. In addition, the step P is folded to save space in the folded state of the vehicle. The vehicle can then be returned to its operating state by performing the above steps in reverse order.

Referring to FIG. 3B, due to the rear pivot axis X_RPWith an angle 2 beta, the rotation of the leg 70 about these axes brings its distal end 76 closer to the symmetry plane SP than its proximal end,thereby allowing a compact configuration of the vehicle 1 in its stored state such that it has a lateral extension T at the front end region of the body member_FCannot exceed or at least not significantly exceed its lateral extension T at the rear end region of the body member_R(FIG. 3A). It will also be appreciated that in the stored condition of the vehicle 1, the rear wheel axle X_WRThe lines become angled with respect to each other as best seen in fig. 3A.

Referring to fig. 3A and 3E, since each rear leg is hinged to a respective side of the rear portion of the body member, the angle of pivoting of the legs from their working orientation to their stowed orientation is so great that in their stowed orientation the distal end of each rear leg is proximate to the front end of the body member and does not project significantly forwardly therefrom. Thus, as shown in fig. 3C, in the stowed state of the vehicle as seen in a side view thereof, each rear leg and associated rear wheel is accommodated primarily between the rear end of the body member and the front wheel, thereby allowing the length of the vehicle along the reference plane in this state to be shortened.

Further, referring to fig. 3E, each rear leg 70 has a shape and width relative to the shape and width of the body member 10 such that in the stowed state of the carrier, each rear leg 70 can overlap in side view of the carrier not only along a majority of their length but also along a majority of their height as described above, allowing the legs 70 not to protrude downwardly from the body member in the stowed state of the carrier.

With reference to FIG. 3D, note that due to the front rod axis X_FBNot in contact with the front pivot axis X_FPCoincident, i.e. the lever 52 is relative to the front pivot axis X due to the hinge member 60_FPOffset OS, so that the rotary motion performed by the rod 52 allows to position the rod 52 with its axis X in the stowed condition of the vehicle_FBForms a very small angle γ with the longitudinal axis L and has its handlebar end 52B located above the seat 32 while being positioned lower away from the reference plane RP by a distance at least not exceeding the reference plane RP and the front wheel W_FIs measured in the direction of the distance between the highest points of (a). In this example, the above design allows the foldable back rest portion 37 to be closed from above on the handle end 52B。

Also, as shown in fig. 3D, in the stored state of the vehicle, the front wheels W_FAnd a rear wheel W_R(only the left one is shown) does not protrude downwardly from the bottom surface 14 of the body member 10.

Turning now to fig. 4A and 4B, there is shown a carrier, generally designated 100, which is configured to function both as a carrier on which a child may ride alone, and as a stroller in which the entire front bar 52 of the carrier may be manipulated by another person (e.g., an adult) from the rear of the carrier. The same parts of the carrier 100 as the carrier 1 described above are indicated by the same reference numerals. In addition, carrier 100 has a rear steering handle 80 and a rear steering mechanism for converting the rotational movement of handle 80 into the rotational movement of front rod 52.

Specifically, the steering mechanism includes: a front rotary member 86 (shown schematically in phantom in fig. 4B) fixedly connected to the front rod 52 and configured to revolve therewith; a rear port 87 disposed in the body member rear portion and configured to be swiveled by manipulating the handle 80; and a pair of right and left steering cable sections 84 (also shown schematically in phantom in fig. 4B) that extend within the body member 10 between the front swivel member 86 and the rear port 87 and that are fixedly attached at one end to diametrically opposite sides of the front member 86 and at the other end to respective diametrically opposite sides of the rear port 87.

The arrangement is such that, since the cable sections 84 are fixedly attached to the front member 86 and the rear port 87, pulling one of the cable sections 84 will cause the front member 86 to rotate about the longitudinal axis X of the front rod 52_FBRotation, thereby causing the front rod 52 to swing, allowing the vehicle to be maneuvered.

The cable section is made of a bendable material, which may be of the same type as used for a bicycle breaking cable, allowing the cable section to be folded at the front pivot axis X when the vehicle 100 is folded from its working state to its storage state_FPThe vicinity is bent.

Fig. 5A shows a carrier 200, which carrier 200 may also be used as a carrier configured to be ridden by a child himself, or as a stroller that is maneuvered via a rear steering handle (not shown) operated by another person. Carrier 200 has substantially the same components as carriers 1 and 100 described previously, except that with respect to some of these components of carrier 200, more details are provided in fig. 5B with respect to one specific way in which these components may be implemented. It should be understood, however, that these components may generally be implemented in other ways. Furthermore, fig. 5B should not be considered to present all the details of these components, but only those described below are shown and are indicated with reference numbers corresponding to the reference numbers used in the description of the vehicles 1 and 100, plus 200. It should also be noted that fig. 5B does not show standard or obvious structural elements. It should also be understood that most of the elements shown in exploded fashion in this figure refer to the right side of carrier 200 (which is best shown in fig. 5A and 5B), which is a mirror image of the left side of carrier 200, and if not otherwise indicated, the same elements shown on the right side of carrier 200 also exist on the left side thereof.

Thus, carrier 200 comprises a hollow shell having right and left shell portions 210, right and left shell portions 210 each comprising a front outer surface 215_FAnd a rear outer surface 215_R(visible only in right housing portion 210) and a front interior surface 215_F' and rear inner surface 215_R' (both visible only in the left housing portion 210 in fig. 5B). As shown in FIG. 5A, when the housing portions 210 are assembled along their edges, they constitute a body member 210, and the front side surfaces 215 of the two housing portions_FDefining a body member front 211 therebetween_FAnd the back side surfaces 215 of the two housing parts_RDefining a body member rear 211 therebetween_R. In this example, the front and rear body portions pass through the body member intermediate portion 211_IntSpaced apart from each other, body member mid-portions 211_IntAre respectively disposed at the corresponding front side surface 215, and an inner surface (not labeled)_FAnd a back side surface 215_RAnd front inner surface 215_F' and rear inner surface 215_R' in the meantime.

Referring to the right housing portion 210 and the left rear leg 270, the rear outer surfaces 215 of the two housing portions are shown in FIG. 5B_REach belonging to a constituent body member rear part 211_RA part of the protrusion 217, the protrusion 217 being formed such that the surface is as described above with reference to the rear surface 15 of the carrier 1_ROriented as described. Each protrusion 217 fixedly holds a hinge shaft 216 having a rear outer surface 215 thereof perpendicular to the hinge shaft 216_R Oriented side 218 and having a free end 219.

Referring to the right and

left leg portions

270, 270 in fig. 5B, each leg portion has a rear leg outer surface 275 and a rear leg inner surface 277, and has a channel 279 extending between the rear leg outer surface 275 and the rear leg inner surface 277, the channel 279 being configured to receive the outer portion 218 of the hinge shaft 216 therein from the leg inner surface 277 and the stop 310 therein from the leg outer surface 275, the stop 310 being configured to be received in the pocket 312, the channel 279 terminating in the pocket 312 and fixedly engaging the free end 219 of the shaft 216, thereby allowing the leg portion to pivot about the shaft while preventing the leg portion from being removed from the shaft.

With further reference to the left rear leg 270 in fig. 5B, each rear leg includes a connection region 278 at an inner side surface 277 thereof, the connection region 278 in the form of a pin projecting therefrom in this example and configured to connect the rear connection end 292B of one of the two longitudinal connection bars 292 such that the connection bars 292 are pivotable relative to the rear leg 270. Each connecting rod 292 also has a front connecting end 292A attached to the hinge member 260, the front connecting end 292A forming part of the front assembly 250.

As shown in fig. 5B, the hinge member 260 includes:

a rear leg-associated portion 266 forming part of the connection mechanism 290 (not indicated) and having two sides to which the front connection ends 292A of the two connection rods 292 are pivotably connected;

a body member association portion 262 pivotally connected to the front body portion 211F (see fig. 5A); and

a front bar associating portion 264, rotatably receiving therein the lower portion 252A of the front bar 252, so that the upper portion 252B of the front bar is not directly connected with the articulation member.

The upper and

lower portions

252A, 252B of the front link 252 are assembled to one another such that when they are locked to one another by the lock 320 (visible in both fig. 5A and 5B), they are fixedly connected to one another to form a single unitary front link unit, and when they are unlocked from one another, they become functionally disconnected, allowing the lower portion to be manipulated by a rear manipulation mechanism described in detail below, and allowing the upper portion to either have a fixed orientation or to be rotatable independently of the lower portion.

As further shown in fig. 5B, the carrier 200 is provided with a right locking mechanism and a left locking mechanism for locking the articulation member 260 in its working orientation, both locking mechanisms being along the front pivot axis X_FPIn operation, each locking mechanism comprises:

a spring-loaded locking element 265 having a pattern of protrusions along its circumference (spring indicated by 267 alone);

a locking cavity 268 formed in the front inner surface 215 of the respective housing portion 210_F' at (visible in the left housing part in fig. 5B) and having a circumferential pattern of recesses corresponding to the pattern of protrusions of the locking element, such that the locking cavity, in its working orientation, can fittingly receive the spring-loaded locking element 265 therein;

a hinge cavity 271 formed in the body member association portion 262 of the hinge member 260 at a side thereof facing the respective housing portion and having a circumferential pattern of recesses corresponding to the pattern of protrusions of the locking element 265; the articulation cavity 271 permanently receives therein the spring 267 and the locking element 265 and is configured to allow the locking element to enter deeper into the articulation cavity when axial pressure is exerted thereon and the spring is pressed accordingly;

a button 261, the button 261 having prongs 281 and a correspondingly shaped channel 283, the channel 283 being formed in the housing portion 210 so as to be at its inner front surface 215_F' and outer front surface 215_FIs configured to receive therein the prong 281 of the button when the button is in its outermost position in the operating state and in the stored state of the carrier 200, and to apply an axial pressing force by its prong 281 when the button is pressed to its innermost positionOn the spring-loaded locking element 265; and

a cover 299, the cover 299 covering the body member associated portion 262 and the front lever associated portion 264 of the hinge member 260 and having an opening 285 for receiving therein a push button 261 to allow a user to access the push button to press it when required.

Thus, in the operating state of the carrier 200, the spring-loaded locking elements 265 are in their locked position, each being accommodated in the locking cavity 268 and extending minimally into the hinge cavity 271. When the state of the vehicle 200 is changed from its operating state to its stored state, the right and left locking mechanisms are operated simultaneously to unlock the hinge member 260 allowing it to pivot about the front pivot axis X_FPFrom its working orientation to its stowed orientation, as described above with reference to vehicle 1.

Unlocking is initiated by pressing right and left button 261, thereby causing tines 282 to exert axial pressure on locking element 265, forcing locking element 265 to move maximally out of locking cavity 268 into articulation cavity 271. In this unlocked position, the locking elements 265 no longer prevent the hinge member 260 from pivoting relative to the body member 210, and they pivot with the hinge member 260 and remain so engaged until the hinge member 260, along with the locking elements 265, pivot back to their working orientation, aligning the locking elements with the locking cavities 268. When this alignment is achieved, each locking element 265 is pushed back into its locked position within the locking chamber 268 by its corresponding spring 267.

Carrier 200 also includes a rear steering mechanism for use with handle 80 (not shown in fig. 5A and 5B) described with respect to carrier 100 shown in fig. 4A and 4B, which converts pivoting movement of the handle into pivoting movement of front rod 252. The operating mechanism includes:

a front rotation member 286 arranged within the front lever associating portion 264 of the hinge member 260, the front rotation member 286 being fixedly attached to the front lever 252 and configured to rotate together with the front lever 252,

a rear port 287 to which a pair of right and left steering cable sections 284 are fixedly attached at one end thereof, and which is fixedly attached at the other end thereof to the front rotary member 286, such that pulling one of the cable sections 284 will cause the front rotary member 286 to swivel with the front bar 252, thereby allowing the vehicle to be steered;

a rear port cup 289, the interior of which merges with a cable channel (not labeled), which cup (shown assembled with the left housing part) is secured to the body member rear 211_RSo that the rear port 287 is received therein in a manner that allows the port to be rotated by the handle 80, and the cable segment 284 passes through the cable channel via the interior of the body member 210 toward the front piece 286.

To ensure that the right and left cable segments 284 will bend as required when the carrier is folded from the operative condition to the stowed condition by pivoting the articulation member 260 with the front lever 252 and the front member 286, the cable segments extend within the body member 210 such that each of them passes between the tines 281 of the respective right or left button 261, allowing the tines to fix the position of the cable segments at which they are to be bent.

Carrier 200 also includes a front bar locking clamp 300, which front bar locking clamp 300 is attached to its fixed frame 236 for locking an upper portion 252B of front bar 252 to fixed frame 236 when carrier 200 is in its working orientation (as shown in fig. 5B), allowing upper portion 252B to have a fixed orientation when the lower portion of the front bar is manipulated.

Finally, as mentioned above and shown in fig. 5A, the pedals P of the vehicle may be mounted to the front wheel W_FAllowing the child in which the vehicle is housed to ride, and as shown in fig. 5C, the pedals P of the vehicle may in turn be mounted to the rear leg-associated portion 266 of the hinge member 260 to constitute a front wheel W_FA footrest arranged closer to the seat arrangement 30 to facilitate use of the carrier 200 as a stroller. The seating unit 30 may be configured to be mounted in at least two positions, one as shown in fig. 5A and 5C, and the other (not shown) proximate the front bar 252.
